When Fleas Bite Humans

When fleas bite humans, they often leave red, itchy bumps on the skin. The bites are highly irritating and can lead to infection. Fleas can also carry dangerous diseases like rickettsia, a serious disease that is spread through contact with the flea’s feces.

Fleas are small, wingless insects that live in the fur and feathers of animals, including humans. They are commonly brought into a home by a pet, such as a dog or cat. Their main purpose is to feed on human blood. Humans can develop an allergic reaction to flea saliva, which can lead to secondary infections.

Fleas can survive for months without feeding, which is why it is important to keep your home free of fleas. Fleas use a saw-like mandible to feed and their saliva contains anticoagulants that promote blood flow. Once they have fed, female fleas lay their eggs. The eggs are light coloured and oval-shaped. Within a few weeks of hatching, the larvae enter the host’s body. Then they emerge from their cocoons and look for blood to survive.

The best way to prevent fleas from getting into the body is to bathe regularly. This way, the fleas cannot swim, so they drown before reaching the side of the bathtub. This flushing action also ensures that fleas don’t lay their eggs in the skin. Other preventative measures include washing bedding and clothes frequently and keeping dead animals out of the yard.
